To-aZZ whom it may concern:

Be it known that I, ROYAL L. BQULTER, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and State of California, have invented certain new and useful Improvements in Razor- Blade Holders, ofwhich the following is a specification. j a

This invention relates to improvements in razor devices, and particularly to razor blade holders adapted to receive and hold razor blades of oliflerent kinds and styles in position for use. The device is especially designed to afford a holder for razor blades of the safety type.

It is an object of the invention toprovide a simple economical razor blade holder having an adjustable razor blade support, whereby blades'of different widths and kinds may be adjustably held for exposing the proper amount of cutting edge for use in shaving.

It is also an object of the invention to pro-,

vide a razor blade holder having equalizing clamping jaws for holding the blades in the shaving position.

It is a further object of the invention to produce a razor blade holder of the safety type having razor blade engaging and holding jaws, and a spring for movably keeping them in razor gripping position," the said spring also operating as a safety guard for preventing the user of the razor from accidentally cutting himself.

It is still a further object of the invention to provide a razor blade holder having an integral handle with razor blade back support, having an adjustable member for controlling the amount of projection of blade, and having pivoted spring actuated blade jaws for removably clamping the razor blade in place. 1 With these and other objects in view, the invention comprises certain novel constructions, combinations and arrangements of parts, as will'be hereinaftermore fully described and claimed.

In the accompanying drawing forming a part of this specification: I

Figure 1 is a side elevationof a razor blade holder, constructed in accordance with the present invention.

Fig. 2 is a top plan view'of the same, the razor gripping jaws being in their normal blade gripping positions.

Fig. 3 is a detail top plan view of the blade carrying portion of'the holder, the

razor holding members orjaws being retracted and the blade removed.

Fig. 1 is a central sectional view taken axially of the blade holding portion of the device.

Fig. 5 is a sectional view taken line 5-5,of Fig. 4.

Fig. 6 is an end elevation of a razor holder looking at the razor backing and supporting end of the device.

The razor blade holder forming the subject matter of this invention is designed to afiord one in which many different kinds of razor blades may be interchangeably employed, the width or shape of the blade not interfering with the holding of the same in shaving position. 1

The details and features of a'preferred form of the said holder will now be more specifically described,'referencebeing had to the accompanyingdrawing, in which 6 indicates a handle having a broad end portion bent and shaped to receive and adjustably hold a razor blade 7 The blade holdingand adjusting means is preferably mounted be tween substantially parallel portions 8 and 9 of the broad end of the handle, said parts being connected by a transverse portion 10. The portion 9 is made broader and deeper thanthe portion 8 for oflering a broad ample support for the razor blade 7. The handle and the parts 8, 9, and 10 forming bent eX- tensionsthereof may be made of comparatively thin material, having the lateral edges upon the thereof bent at right angles thereto, to form Patented Feb. 4, 1919.

strengthening flanges 11, 12, 13 and 145,

whereby the requisite stiifness may be given the frame of the device.

The central portion of the part 8 and the handle. adjacent thereto, is preferably cut away, and a portion of the cut-out material is bent to form a tongue15, which is brought to a plane approximately parallel'with the plane of the portion 10. A screw 16 is mounted in the free end of the tongue 15, and in the portion 10, so that the said screw is substantially parallel with the body portion of the part 9. A flanged nut 17 is threaded upon said screw, the flanges thereof affording a groove 18, in which fits a socket portion 19 formed upon an adjustable blade supporting bar 20. The flanges of the nut 17 are usually knurled or serrated upon the edges thereof as at 21 to facilitate the turning of the nut in adjusting the same upon the screw against the surface of the blade supporting back portion 9, whereby it 1s movab ly held in position with respectto'thead usting nut 17 Projections 22 are formed upon the long.

edge of the said bar 20, and project through slots 23 formed in the portion 9, whereby, the bar is guided in its adjustment along the screw. A razor blade resting uponthe bar 25, having operatingarms 26 and 27', projectingfrom the outer ends thereof, approximating at right angles thereto, as clearly shown in Figs. 2 and 3 of the drawing.

The blade engaging portions of the: jaws are provided with hearing edges 28, which extend parallel to the portion 9, and the bladeresting against the same. The aws are adapted to be movably drawn against the blade or the portion 9 behind the same by a spring 29, the ends of which aresecured to projections 30 formed at the outer ends of the jaws 24 and 25. The said projections 30 may be stamped outwardly from the ends of the jaws, and bentuponthemselves as shown in Figs. 1 ands, the said projections-having a series of perforations 31 therein through which several turns of the spring 29 are placed for fastening'thesaid spring to the said jaws.

The spring may be readily put in place. by turning the same until the ends thereol have been threaded through the apertures 31 as indicated in thedrawing. Thespring is so located that its line of pull upon the outer ends of the jaws comes betweenthe axis of thespring 16 and the portion 9, whereby the jaws will normally be pulled inbla-d'e holding positions.

It will be evident by reference to Fig; 3 of the drawing, that by pressingLupon-the outer ends of the arms'26 and 27, simultaneously, the jaws 24 and 25' will be retracted from their. engagement with the razor blade, at whichtime the-blade may be removed and a new one inserted. A nut 32 is applied upon the screw 16 inside the jaws, for-preventing the jaws fromslipping backand. forth on the said screw. The nut 32 is preferably provided with. a hub portion 33, which is made of suflicientlength to permit the nut to be tightened. against-the tongue 15', without interfering. with the free movement of the jaws 24:and25'. Thehead ofthe'nuti is thus spaced from. the tongue 15, by the said hub fora distance a little greater thanthe thick.- ness of: the two jaws: 24; and% 25:.

The proj ectionsfitl'which support the-spring 65 29,;a-re: carried outwardly'sufificiently' to hold said spring near the edge of the razor blade, thus permitting the spr ng to act as a safety guard and'tend to prevent danger of cutting oneself by the use of the device. The said spring has thus a double function, of a blade guard, and a jaw actuating means.

As shown in Fig. 6 of the drawing the body portion-of the part 9 is preferably cut away at 34, a suflicient distance to properly expose enough of the razor blade to permit of the shaving operation.

In connection with. the blade: supporting bar 20, the socket. portion 19 is made with its forked part sufficiently elongated as at 35, to have an ample-bearing in the groove 18. toprevent the said bar 20' from tipping, and thus to keep it substantially parallel with theportion 10 of the holder. Theprojections 22 in addition to acting as guides for the bar 20, also perform an important function in supporting very thin razor blades, for said projections preventing any possibility of the blade slipping down between the edge of the bar 20 and the portion- 9 of: the handle, as will be readily understood. Without. such projections this might happen with. any thin: blades, and especially such as are sharpened on both edges.

It will be evident that the razor blade holder above-described is ofsimple construction and. capable of economical production, and that itis readily adaptable for the use of any kind of a razor blade of the style employed in asafety razor structure.

It will be evident that thebar 20 can be quickly adjusted for blades of any width, and that the gripping jaws afford a quickly operating mechanism. for gripping. or releasing a blade. The mounting of the two jaws, adaptedrto be brought together by the spring 29, gives an equalizing effect, whereby each jaw exerts substantially the-same pres sure upon the blade asthe other jaw. The spring need not be very stiff, or of great strength to hold the razor blade properly for shaving, especially asthe'jaw 2O positively supports the razor blade in true position, with. respect to the upper edge of the portion 9, and the guard formed bythe spring29.

It will be evident that the minor details of construction may be somewhat altered within the. scope of. the invention, andv that mechanical equivalents may be. substituted for some of the parts, without departing in the least from the spirit-of said invention.

In employing a spring guard as above shown and described, itiwill be observed that such aguard has a slight yielding quality when pressed against the face, so! that. the blade becomes moreprominent and thus performs. the shaving. operation more readily,

especially upon uneven! portions of the face.
